The Rur (German; in Dutch and French: Roer), — not to be confused with the Ruhr — is a river which flows through portions of Belgium, Germany and the Netherlands. It is a right (eastern) tributary to the river Meuse. About 90% of the river is in Germany.
The Rur rises in the Hautes Fagnes/Hohes Venn National Park, near the 696 meter-tall Signal de Botrange in Belgium at an altitude of 660m. South of Monschau it flows into Germany, through North Rhine-Westphalia. It flows first through the northern part of the Eifel hills.
After 39 km it reaches the Rurstausee, the second-largest artificial lake in Germany. After approx. 160 km it flows into the Netherlands, and at its 170 km mark it flows into the river Meuse at the city of Roermond.
Major tributaries of the river Rur include the Inde and the Wurm. Cities along the Rur are Monschau, Heimbach, Nideggen, Düren, Jülich, Linnich, Hückelhoven, Heinsberg (all in Germany) and Roermond (Netherlands).
The Rur represented an important front in the Allied push towards Germany at the end of the Second World War.
Operation Blackcock was the code name for the clearing of the Roer Triangle formed by the towns of Roermond, Sittard and Heinsberg. It was conducted by the 2nd British Army between 14 and 26 January 1945. The objective was to drive the German 15th Army back across the Rivers Rur and Wurm and move the frontline further into Germany. The operation was carried out under command of the XII Corps by three divisions. The operation is relatively unknown despite the sometimes fierce battles that were fought for each and every village and hamlet within the "Roer Triangle".
Between 16 December 1944 and 23 February 1945, the U.S. Ninth Army was unable to advance across the Rur during Operation Queen, because German forces controlled dams close to the river's source in the densely forested region of the Hohes Venn. This meant Axis forces could potentially blow the dams, releasing enough water to wash out an Allied assault. At the same time, the German Ardennes Offensive meant any further westward push would leave Allied forces stretched and supply lines exposed. Eventually the counteroffensive was overwhelmed and German engineers, under pressure of aerial and artillery bombardment, released the dams. As the flood waters began to subside, Allied forces crossed the Rur in rafts in the early hours of February 23, 1945, as part of Operation Grenade.
The Rur is the only real white water river in Northrhine-Westfalia. The upper section above the Rur reservoir (German: Rurtalsperre Schwammenauel) offers 20 km of white water ranging from class III(+) to I.
Paddling on the Middle Rur below the Rur Reservoir is dependant on the release of water from the Rur dam and is subject to registration with the German paddlers club DKV. For environmental protection reasons this section of the river may only be paddled between 15 July and 28 February. Despite these restrictions it is frequently visited by individual paddlers and boat rental companies for its natural beauty.
The town of Monschau is the venue for the yearly International White Water Race which was held on 17 March 2013 for the 58th time.

From 1795 until 1815, when Belgium, the Netherlands and parts of Germany were incorporated into France, there was a département named after the river Rur, see Roer (département). From Heimbach to Linnich, the tracks of the Rurtalbahn (Rur Valley Railway) run along the river.
